Signalling on low-voltage electrical installations in the frequency range 3 kHz to 148,5 kHz and 1,6 MHz to 30 MHz - Part 4-7: Portable low voltage decoupling filters - Safety requirements

Publication date:   Aug 10, 2006

Scope

This European product safety standard applies to the filter part of portable devices for household and
similar uses (hereafter referred to as portable decoupling filters) consisting of the filter part, a plug or an
appliance inlet or a provision for connection by terminals or with a non-rewirable cord and one (multiple)
socket-outlet or an appliance outlet. They are intended for single-phase circuits for nominal currents not
exceeding 16 A and for nominal voltages not exceeding 250 V a.c. to neutral operating in the frequency
range 3 kHz to 148,5 kHz and from 1,6 MHz to 30 MHz.
The filtering functions are described in EN 50065-4-1.
This standard does not cover phase couplers.
Portable decoupling filters shall not be used as part of the fixed installation, where EN 50065-4-2 applies.
Plugs and socket-outlets connected to the filter part and plugs and socket-outlets integrated with the filter
part shall comply with the relevant national standard(s).
Appliance inlets and appliance outlets connected to the filter part shall comply with the relevant parts of
the EN 60320 series. Appliance inlets and appliance outlets integrated with the filter parts are not covered
by this standard.
This standard can be used for portable mains communication devices when no other product standard
exists.
This standard can be used for other portable mains filters other than those described in EN 50065-4-1
when no other product standard exists.
Filters including batteries are not covered by this standard.
